Application letl September 1G, 191.0.

To all v11:11am zt may .concern Re it known that i. ERNEST lineman. a citizen ot the Vni'tetl States. and a residentV ot Tampa. in the countwY of Hillshoro and State olE Florida, have invented a new and ltnnwovcd TlnuSt-learing, ofi which the 'iollowing; is a full, clear, and exact description.

Thisv invention relates to thrust hearings Jfor une in connection with prime movers.l pumps and other machines. and has rct'erence more, particularly to a thrust hearing' which comprieea a removahle collar adapted to receive a shaft, and haviutr at thc end an annular recess, ahont the Shaft. and hearing` washern located in the receezs and adapted to receivecnd thrust 'lf'roin an adjacent machine. part.

The object. of the, invention is to provide a simple, strong and ctlicicnt thrust hearing' which can be used with centrit'ugal pumps. prime movers4 and other machu; y which can he convenientlv located lct\\'ecn machine elements, which when .eo lofatetl can he ea tilv removed and rephiced withoutdisturhing; the machine. elements. in which tta-hearing' ineniliers receiving); dircctlv the end thrust' are securely held in place. and in which the hearing memhere are so construct ed that thorough lubrication can lie etl'ecled.

rThe invention consists in thtl conatructi/.m and combination oi parI to he more fully dcecriht-d hcreinatiter and particularl)7 eet vl'orth in the claims."

llett-srence is to he had to the accomlmnvinn' drawinne lorn'iing` a pariy o't this specification. in which similar clniractere` of retcrcnce indicate ('.orreeponding partl in all the views. and in which* Figure 1 an end elevation ot a n cmhodinient ot" my invention: lia", Q is a transverse :section ot the hearing', on the line 2N2 oli Fig. it: lfil. if is a longitudinal Section ol the hearing, showing` the Same in place, upon 'a :.hat't: and Fig, 4 is a perspective. view ot one ot thc hearing` washers.

lettore proceedingv to a more detailed exphtnat-ion ot my invention it should he clearly underst'twd that. while the thrust'. hearing` is ,mrticularl);Y useful in connection with machines such as centriliugjal pumpe. it cau also he advantageously elnploved under other circumstamcis. where it' ta necessary to taltcup end thi-untn upon a uitahlo hearing. l prcicer to 'aehion the hem-ing nn-ml err`y or washers from l ras hutwany other material adapted l'or the pur- Speeeaton of Letters Yatenti Patented fitug. 2li, 1912.

pow can also he ennjilovccl. Certain ol the detail@ ot construction. shown 'lor example herewith. torni no part o'l2 the invention anch can he varied in accordance with individual preicrcnce and special conditions. without departing Yfrom the underlying' spirit' of' the invention.

Referring more particularlv to the drawings, 1 employ a collar 1t), compri. ine' two halven` or SectiomI 11. and 1Q. which are oit' suhstaiitially senii-cylintlrical cross section. Each section. at thc ende, i has annular tlanfrehl 13 and .tf-t, which are radially7 extended and are connected hv :strengthening rihs 15. The sections 11 and 12 have at the longitudinal edges, tlanges 1t' adapted to engage when the sectionsl are assembled, and having; ministering.: openings lt-hereihrongh which receive retaining and clamping holte; 1S, hy means ot which the collar is secured upon a shaft 1S) or the like.

The end flanges .1'1V o'l2 the collar sections have at the peripheral edges, exlenions 20, disposed in thc direction olf the length of the collar and `forming ahout. Athe central openingi ot the collar an annular recess which is concentric with the `sha'tt 19 or other nicmher upon which thc collar is secured. I cmplo)r l Efiring memhcrs '21 each of semiannular form. and 'torming together, a bearing ring. The ringprojectV slightly beyond the flange extensions 20, as is shown in Fig. 2%. and receives the end thrust of an adjacent machine part.

'the hearing lnemhersA have at, the inner edge. atl st':ti1ti:tllv midway hetwecn the ends. aroovee 22. VUn the outer` faces the members.' have circular lgrooves 23 which, when the hearing members are assembled, form two intersecting circles, eccentric with the hearingY ring'. The circles intersect at the junction ot` the twomemhern, as is shown in Vig. 1. and cach also intersects one of the `grooves; 22. rl`he members 21. aty their' inner edges. have notchee 2.4, which when the men'il'iere` are asssen'ihled torni grooves intersecting lulnicant. grooves at the rear or inner lares. olithe, members 21, and inclicaterlin dotted outline in Fig. 1.

llaving thus descriliietl my invention, 1 claim an new, and desire to secure by Letters. latent:

t. A thrust, hearing, coun'n'isingr a collar ornnal ot sentirviindrical sections having if i end :"iangreeI and at their longitudinal edges pertured tlanges. one end tlange having on with the opening thereof, a sectinalbearing ring fitting in the recess of the end flange of the collar with a'portion projecting beond the face of the said flange, said ring aving rooves in the Wall of the opening atA the a utting portions of the sect-ions and midway between said portions and eccentric circular grooves on' each face, the. grooves on one facel intersecting each other at the abutting 'portions of the sections and connected with the grooves midway between saidabutting portlons, and the grooves on the other face intersecting eachother midway between the abutting portions and connected with the grooves at the said abutting portions, and bolts passin ithrough the apertured flanges of the colar and cla-mping the sections of the collar together and the y bearing ring in the recess of said collar.

2. A thrust bearing, comprising a collar formed of two Serin-cylindrical sections having end vlangesand at their longitudinal l edges apertured flanges, one end flange having on its outer face an annular recess concentric with the opening thereof, a sectional bearing ringI fitting in the recess of the end flange of the collar, said ring being provided; with grooves in the wall of itsopening and with grooves in its faces communicating with the first named grooves, and bolts passing through the apertured flanges ofthe .collar and clamping the sections of the collar together and the sectional bearing ring in the recess of said collar,

In-testimony whereof I have signed my `name to this specification in the presence ofl two subscribing witnesses.
